Server-side processing can be used to show large data sets, with the server being used to do the data processing, and Scroller optimising the display of the data in a scrolling viewport.</p><p>When using server-side processing, Scroller will wait a small amount of time to allow the scrolling to finish before requesting more data from the server (200mS by default). This prevents you from DoSing your own server!</p><p>This example shows Scroller using server-side processing mode and 5 million rows. <strong>Important</strong> This particular example uses <a href="//datatables.net/reference/option/ajax"><code class="option" title="DataTables initialisation option">ajax<span>DT</span></code></a> as a function to 'fake' the data to show Scroller's ability to show large data sets. It does not have a real database behind it! You would normally not use <a href="//datatables.net/reference/option/ajax"><code class="option" title="DataTables initialisation option">ajax<span>DT</span></code></a> as a function to generate data, but rather as a url for where to fetch the real data!</p><p>In this example we also enable the <code>loadingIndicator</code> option of Scroller to show the end user what is happening when they scroll passed the currently loaded data.</p></div><table id="example" class="display" cellspacing="0" width="100%"><thead><tr><th>ID</th><th>First name</th><th>Last name</th><th>ZIP / Post code</th><th>Country</th></tr></thead></table><ul class="tabs"><li class="active">Javascript</li><li>HTML</li><li>CSS</li><li>Ajax</li><li>Server-side script</li></ul><div class="tabs"><div class="js"><p>The Javascript shown below is used to initialise the table shown in this example:</p><code class="multiline brush: js;">$(document).ready(function() { $('#example').DataTable( { serverSide: true, ordering: false, searching: false, ajax: function ( data, callback, settings ) { var out = []; for ( var i=data.start, ien=data.start+data.length ; i&lt;ien ; i++ ) { out.push( [ i+'-1', i+'-2', i+'-3', i+'-4', i+'-5' ] ); } setTimeout( function () { callback( { draw: data.draw, data: out, recordsTotal: 5000000, recordsFiltered: 5000000 } ); }, 50 ); }, dom: &quot;rtiS&quot;, scrollY: 200, scroller: { loadingIndicator: true } } ); } );</code><p>In addition to the above code, the following Javascript library files are loaded for use in this example:</p><ul><li><a href="../../../media/js/jquery.js">../../../media/js/jquery.js</a></li><li><a href="../../../media/js/jquery.dataTables.js">../../../media/js/jquery.dataTables.js</a></li><li><a href="../js/dataTables.scroller.js">../js/dataTables.scroller.js</a></li></ul></div><div class="table"><p>The HTML shown below is the raw HTML table element, before it has been enhanced by DataTables:</p></div><div class="css"><div><p>This example uses a little bit of additional CSS beyond what is loaded from the library files (below), in order to correctly display the table.
